Echarts之内嵌圆环图v5.1.2
相比v4,v5有些许变动。我也没看官方文档,就对着浏览器开发者工具报错的地方一个一个调的,又综合了别人的经验,代码如下
放在drawPieAll function下
drawPieAll() { // myChart paint more times, it will warn if ( this.myChart != null && this.myChart != "" && this.myChart != undefined ) { this.myChart.dispose(); } this.$nextTick(() => { this.myChart = echarts.init(document.getElementById("pieAll")); let dashedPic = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAM8AAAAOBAMAAAB6G1V9AAAAD1BMVEX////Kysrk5OTj4+TJycoJ0iFPAAAAG0lEQVQ4y2MYBaNgGAMTQQVFOiABhlEwCugOAMqzCykGOeENAAAAAElFTkSuQmCC"; let color = ["#FF8700", "#ffc300", "#00e473", "#009DFF", "#a794c8"]; let chartData = [ { value: this.getAmount("statement", "正常"), name: "正常" }, { value: this.getAmount("statement", "缺卡"), name: "缺卡" }, { value: this.getAmount("statement", "早退"), name: "早退" }, { value: this.getAmount("statement", "迟到"), name: "迟到" }, { value: this.getAmount("statement", "补打卡"), name: "补打卡", }, ]; let arrName = []; let arrValue = []; let sum = 0; let pieSeries = [], lineYAxis = []; // 数据处理 chartData.forEach((v, i) => { arrName.push(v.name); arrValue.push(v.value); sum = sum + v.value; }); // 图表option整理 chartData.forEach((v, i) => { pieSeries.push({ name: "考勤情况", type: "pie", clockwise: false, radius: [65 - i * 15 + "%", 57 - i * 15 + "%"], center: ["30%", "50%"], label: { show: false, }, data: [ { value: v.value, name: v.name, }, { value: sum - v.value, name: "", itemStyle: { color: "rgba(0,0,0,0)", }, }, ], }); pieSeries.push({ name: "", type: "pie", silent: true, z: 1, clockwise: false, //顺时加载 radius: [65 - i * 15 + "%", 57 - i * 15 + "%"], center: ["30%", "50%"], label: { show: false, }, data: [ { value: 7.5, itemStyle: { color: "#E3F0FF", }, }, { value: 2.5, name: "", itemStyle: { color: "#e3f0ff", }, }, ], }); v.percent = ((v.value / sum) * 100).toFixed(1) + "%"; lineYAxis.push({ value: i,

加强版——叠加直360°
加入了一个计算旋转角度的玩意
